I just came across the range slider option in ArcGIS Pro (Get started with the range slider—ArcGIS Pro | ArcGIS for Desktop) which works fabulously for developing Climate Change related coastal flood scenarios (see picture).
The Range Slider very easily enables us to produce flood maps which are available for other parts of the world already - but which were produced with complicated Java Scripting (e.g. NOAA's Sea Level Rise Viewer, and the Australian CoastalRisk Viewer) However, when I tried to push my ArcGIS Pro Range Slider maps online, I found that the Range Slider is not at all available in ArcGIS Online! :-(
I tried a work around using the Time Slider, but the results are not very satisfactory, as I had to persuade AGOL that my flood levels are actually years. Converting a flood level of 4.5m into a year 4500 looked quite clumsy in the output...
Therefore, PLEASE could you implement the Range Slider into AGOL as well?
It would make our Climate Change adaptation work in Africa SO much easier.
Many thanks in advance!
